In plain English

Eating up to 50 grams of butter per day does not change the risk of death from any cause in middle-aged adults from southern Sweden.

See the scientific wording

Butter consumption is not associated with all-cause mortality in middle-aged adults from southern Sweden, even at intakes up to 50 grams per day, suggesting that high-fat dairy fat from butter may not independently influence lifespan in this population.

Why this might work

When people eat butter, the fat gets broken down and used for energy or stored in the body without causing harmful changes in blood sugar, inflammation, or cholesterol levels that would shorten life.

What the research says

1 study
  1. Study: Dairy Consumption, Lactase Persistence, and Mortality Risk in a Cohort From Southern Sweden

    The study found that people who ate butter didn’t die more or less than those who didn’t, even if they ate a fair amount daily. So, butter doesn’t seem to make people live shorter or longer lives in this group.
